We're provided a file named `ihatejs.hs`. No other information is given.

The code was minified and obfuscated, so I unminified it first, and tried to look at it, but couldn't understand much because of the level of obfuscation. So, after a while, I just went on and executed the js file to see if something happens.
$ node ihatejs.js
Voila! That was easier than expected!
